b5e60f0d | 21 | * @brief Playlist support for Disobedience |
fc36ecb7 | 22 | * |
f0bd437a | 23 | * The playlists management window contains: |
b5e60f0d | 24 | * - the playlist picker (a list of all playlists) TODO should be a tree! |
f0bd437a RK |
25 | * - an add button |
26 | * - a delete button | |
7fe2807d | 27 | * - the playlist editor (a d+d-capable view of the currently picked playlist) |
b5e60f0d RK |
28 | * - a close button TODO |
29 | * | |
30 | * This file also maintains the playlist menu, allowing playlists to be | |
31 | * activated from the main window's menu. | |
32 | * | |
33 | * Internally we maintain the playlist list, which is just the current list of | |
34 | * playlists. Changes to this are reflected in the playlist menu and the | |
35 | * playlist picker. | |
36 | * | |
